The answer is c because 15 *14=210.
When you add the equations in (a) you get 7x+y=24.
When you subtract the equations in (b) you also get 7x+y=24.
That means to solve both systems you can work with the same equation. However that is not enough. We must have two equivalent equations. We found only one.
Notice however that in the (b) we can take the first equation and divide every term by 2. When we do this we get 4x-5y=13. That’s the first equation in (a).
So both systems can be solved by working with the same two equations. These are 5x-5y=13 and 7x+y=24. And since we have two equations and two unknowns (the number of equations matches the number of variables) there is only one solution — one x and y that would make both systems true — solve both systems.
Basically we showed the systems are equivalent!
In order: 32°, 78°, 71°, 54° , 154°, 113° , 81° , 77° , 91° , 83° , 159° , 86° hope this helps just color in order of the degrees given and it will lead you to the end.
Answer:
150x^2+2340x-50000
Step-by-step explanation:
5[6x(5x+78)-10000]
5[30x^2+468x-10000]
150x^2+2340x-50000
1) 11 1/8
2) 5/7
3)it would be 233/3 but since that isn't your option try going with 23/3
4) 10 / 16
5) 9/3 = 3 (aka 3/1 ) then 3/9 = 0.3.
Answer for number 5 ⬇
Therefore 9/3 would be your greatest
~the fractions doesn't equal each other~{meaning that the equal sign wouldn't be your answer} ~
~3/9 Would be lesser than 9/3~
~just make the fraction into division .it might help ~
~~~~~~~~~~~~~`~~~~~~~~~~~~~~~~~~~~~~~~~~~
For improper fraction just multiply and add
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Looking for the equivalent of the fractions... try dividing as well
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Example of a improper fraction
Problem : 12 3/5
Work: 12(5) = 60
60 +( 3 )= 63
Answer : 63/ 5
(note: don't worry about the example .... its not apart of the questions you asked.. but you can if you want to ... don't get me wrong.. if it was helpful you can use it )
